Definitions

  • the object of the invention is to provide for the renegotiation of the parameters of the traffic contracts dynamically during the established communication.
  • Said step a) of prediction can be implemented from the value taken by the length of the virtual queue at the time of renegotiation, from the value taken by the output rate of said queue in the period preceding the moment of renegotiation and information that characterizes traffic in at least the period preceding the time of renegotiation.
  • the said characteristic quantity or quantities of the traffic may be or may include the number of bits or cells of the traffic in each time interval. They can also be or include the arrival time between two consecutive traffic cells.
  • Fig. 2 we see the curve representative of the variation of the length X of the file 10 as a function of time. Until the instant t 0 of the renegotiation, the curve is in strong lines to show that it is the length as it was which is represented. After the instant t 0 , the curve is subdivided into two curves for two flow rates at the output of the queue 10 taking respectively the constant values R1 and R2. These two parts of the curve are plotted in dotted lines to show that it is the length of the queue as it would actually be after the time t 0 for output flows R1 and R2 respectively. Thus, the observer is placed at time t 0 .
  • the predictor 20 or 20 ′ can predict for each flow R the maximum line lengths L max (R).
  • the predicted maximum queue lengths L max (R1) and L max (R2) have been shown.
  • the peak peak PCR and the sustained rate SCR are predicted, at each time t 0 , for the next period of 10 s.
  • an admissible CLR cell loss rate of 10 -9 a queue size of 1 Mbit and a maximum R link speed of 155 Mbits / s.
